Archived logs maintanance

Previous DBA did not set up any archived logs maintanance here si I am in the process of developing a process that will store old archived logs on DVD. We're on 9.2.0.5 on Win2K. Here is what I am thinking: after each cold backup, do alter system archive log current to archive the latest redo, zip all old logs and copy them to DVD, then delete them from disk. Can someone share a script or info on this?
